How do I download a copy of the extension filed within Turbo Tax

I just tried and it worked. I found it under My Docs (for me its under the 2017 taxes ) and it'll take you to to a page that has the 2018 extension as well as the 2017 tax return. It left me download my 2018 extension without a problem. Not sure if its not working for anyone else if this is your first time using TurboTax unlike myself.
